Abstract

The invention discloses a method and a system for topic keyword self-adaptive expansion on a social network platform. According to the method and the system for the topic keyword self-adaptive expansion on the social network platform, implicit keywords and keywords of relevant topics are extracted to build a keyword expansion vocabulary through the analysis of the correlation among social network information contents. The method includes the following steps: labeling a small amount of keywords to build a seed keyword vocabulary, collecting sample information to build a corpus through incremental self-feedback, obtaining word frequency through the sample information, obtaining relevant words which have high correlation with the seed keywords through the word frequency and multi-layer filtering algorithm, and selecting suitable words and adding the words to the keyword expansion vocabulary. The method and the system for the topic keyword self-adaptive expansion on the social network platform are different from a traditional webpage class keyword expansion mechanism, and are based on the characteristics of the social network information contents, and have higher flexibility and self-adaptivity to the selection of the keywords.

Description

technical field [0001] The present invention relates to the field of social networks, in particular to a method and system for adaptively expanding topic keywords on a social network platform.
